WebbThe theory is compared with experimental data on protein and insulin crystallization (growth dynamics of the proteins lysozyme and canavalin as well as of bovine and porcine insulin is considered). The hat-shaped particle-size distribution functions for lysozyme and canavalin crystals as well as for bovine and porcine insulin are found. Webb1 apr. 1998 · This paper provides a detailed description of a simple method to obtain large protein single crystals inside glass capillaries. The method is based upon the properties of gels, which are used to hold capillaries containing the protein solution, and also to act as the mass transport medium for the precipitating agent.
WebbWith an ellipsoidal protein model and an analytical framework involving colloid diffusion theory, we separate the rotational Dr(φ) and translational Dt(φ) contributions to D(φ). The resulting Dt(φ) is described by short-time self-diffusion of effective spheres. Protein self-diffusion at biological ... Journal of Applied Crystallography 1.
